FEED-WATER HEATER 0B CONDENSER.

Application filed January 18, 1928. Serial No. 247,584.

lVly invention relates to feed water heaters or condensers for utilizing exhaust steam from steam engines, pumps, etc, and for heat transfer from one liquid to another and for raising the temperature of air by steam, hot gases or hot liquids for use in dwellin houses, public halls, etc, and the principal objects of my invention are; first, to provide an apparatus of this class in which there is a continuous thin flow of liquid held in one direction through the apparatus and a continuous thin flow of vapor fluid for changing the temperatu re ot' the first mentioned fluid flowing in the opposite direction through said apparatus; second, to provide an apparatus of this class which will reduce to a minimum the liability of getting out of order by reason of expansion of and contraction and crystallization of the main conducting elements; third, to provide an apparatus of this class which may be readily taken apart for cleaning, repairing and the like; fourth, to provide an apparatus of this class in which the parts will not readily crystallize by reason of vibration; fifth, to provide an apparatus of this class in which some oi the spacing plates are reinforced and provided with separators for the fluid passing therethrough; sixth, to provide an apparatus of this class the separate parts of which will not corrode together due to the continuous action of the expanding and contracting members; seventh, to provide an apparatus of this class that causes the liquid to become turbulent thereby causing said liquid to be broken up and causing a more even distribution of the heat transfer through the body of the liquid; eighth, to provide an apparatus of this class that will not become air locked due to the design of the heat transfer lates; ninth, to provide a novelly constructe apparatus of this class; and, tenth, to provide an apparatus of this class which is very simple, economical of construction, durable, efiicient in its action and which will not readily deteriorate or get out of order.

lVith these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application in which:

Figure 1 is a transverse sectional view through 1--1 of Fig. 2; and Fig. 2 is a sectional view on the line 2--2 of Fig. 1.

Similar characters of reference refer to similar parts and portions throughout the views of the drawings.

A casing comprising the main casing memher 1, side plates 2 and 3 which form baffle supporting members, butlle members 4 and 5, reinforcing ribs 6 and 7, and continuous zigzag fluid directing partition plate 8 const1- tutes my apparatus in its preferred form.

The main casing member 1 is preferabl a rcctangularly shaped, hollow casing member provided with fluid inlet ports 1 and 1 and fluid outlet ports 1" and 1 and rovided in its side walls with a plurality o notches 1' as shown best in Fig. 2 of the drawings. It is provided around its outer side with a flange 1 which is provided with a plurality of holes adapted for the bolts 1". Secured to the 0pposite sides of this member 1 arethe side plates 2 and 3,,which form ballle supporting members, the plates being secured to the member 1 by means of the bolts 1 which pass through theflanges 1', as shown best in Fig. 1 of the drawings, thus forming a complete casing for my feed water heater or condenser. Secured to the inner sides of the members 2 and 3 are the baffle plates 4 and 5 which are preferably secured thereto by welding. It will be noted'that the upper bafile plate on the member 2 and the lower baffle plate on the member 3 are shorter than the remaining batlle plates, and that the remainin g baflle plates extend nearly across the space between the plates 2 and 3. The baflle plates 4 which are secured to the side plate or support 2 are provided on opposite sides with rib members 6 which are positioned intermediate the ends of the baflle plates 4 and 5 andextend a suitable distance along each side as shown best in Fig. 1 of the drawlngs and they are placed in spaced relation to each other for i directing more uniformly the fluid through the apparatus, and serve to reinforce the interior of the structure.

Interposed between the edges of the rib members and around the ends of the baille.

plates is a thin continuous zigzag plate partition 8 which extends from the upper side of the casing 1., some distance from the side with the outlet 1 and is welded to the casing at both top and bottom sides and the ends forming a contimuirus zigzag guide tor the fluids moving: in both directions through the appa 'atus.

Thus it will be noted that the member 8 is secured to the using 1. in general zigzag; form from the upper to the lower side, forming a zigzag partition in said casing 1 and the battle plates l: and 5 are spaced at their inner edges some distance from the bend and leaving a par-samura so that these battle plates form a guide for the fluid in opposite directions, it being noted that thesides of the battle plates 4: and are positioned in notches 1 in the side walls oi? the casing), 1 with su't? ticient play around the same to permit morement with the expansion and coi'itraction and slight vib alien. The reinforcing and distributing rils 6 and 7 are spaced at their outer edges a slight, distance from the member 8 to permit slight movement hut serve as reinforcement when the more under pressure.

It will be noted that this apparatus run he used for heating or cooling; vapors or liquid fluids and that the vapor may more in either direction through the ap Jaratus ind the liquid in either direction as long is it is in the OppOiSllG direction; or, both the apor and fluid may more through the apparatus in the same direetiim, if desired, although it is preferred that one he moved in the opposite direction to the other. It will also be noted that the inlets and outlets of the 'tluid and vapor or either of them may be positioned in the members 2 and t) as well as in the casing 1, it being; obvious that it is immaterial where theseinlets and outlets are positioned so lon as they con'mninicate with the space near the opposite ends and on opposite sides ot the zigzag partition 8.

Though I have shown and described a particular construction, con'ibiniliim and arrangement of parts and portions, I do not wish. to be hunted to this particular construction, combination and arrangement but desire to include in the scope of my invention the constrijiction, combiinrtiim and arrangement substantially as set forth in the ap' pended el aims.
